Hi AK,
With the latest AltUI version (v2129) I noticed that my Z-way communication seems to be having an issue. So I checked the logs (openLuup v17.3.9) after a reload and ...

Lots/perhaps all of my Z-way devices are not reporting but scenes are operating as my outside lights are coming on and off per schedule. Just don't see updates (all my sensors indicate the last update was yesterday when I performed the AltUI upgrade). Let me know if you need more detail.
Thanks
